The antipersonnel operation is basically conducted to obtain an intel. The information can be acquired by stealing, though it is not categorized as an antipersonnel. It is meant to gain an information directly from their target and once its channel is concretely established, this relationship is availed for other types of the operation. Therefore, the antipersonnel is the first step to obtain a secretive intel.
The assetization is an operation to acquire the intelligence target as an asset. There are many types of names for this category, such as a collaborator or double agent.
A collaborator is a type of the asset who is a government officer to provide a secretive information to the spy of another country. This officer can be availed for an operation as well. On the other hand, the double spy is a special term for the same government officer who works for the intelligence organization to breach an intel to another. In any way, both of them are generically classified as a spy.
The intelligence has acquired a general asset, not working for the government, including an informant. After all, the spy has targeted not just counterpart governments, but also terrorists and crime organization, furthermore to the public company and economic entity. They have their own assets in those organization, whose naming is varied by their types, though all of them are assets of the intelligence, categorized as a spy.
Generally speaking, the most of assets know that they are as such, but not all of them have recognized its fact. For example, the target can be framed by the honey trap, whose partner is actually a spy. If that is the case, the subject might not realize the whole orchestration, but the intel has been leaked from this agent. In this case, this target can be categorized as an asset, but not recognizing as such.
On the other hand, there are many people who are willing to become a spy. There are also various reasons for that and some of them provide an intel to the spy with an exchange of the money, which is categorized as an informant.
Some of the double spies have provided their secretive intel to others with an exchange of the information from the counterpart. The CIA has the most affluent budget and personnel, hence the spy of other countries can get a deeper insight if providing their own to the agency. This double spy can be careered up as gaining a special information.
If this individual assumes an influential position to decide the national direction, the CIA can get an opportunity to control this targeted country through their asset.
There are other cases that the target has been driven to become one of the assets without any intentions. For example, the target might be fallen into an unethical or illegal conduct through the honey trap, no way out just to follow a spy order.
It is more general just to frame the subject with a crime or traffic accident. When the intelligence sets up an accident and the target actually causes a traffic accident as planned, this individual faces with the legal punishment and compensation.
The spy asks them to become an asset with an exchange of lifting those charges. If not, they are blackmailed to spend some time in the jail with a huge payment for the damage.
If this is not an accident but a crime, the spy has more leverages. In this case, the subject might be locked up much longer, hence there are more people to choose a way to become an asset.
There are categorically two types, one of which is an acquirement of the criminal if this individual is worthwhile for their spy operation.
The other is more probable but the spy has originally framed their target to commit a crime with an instigation. It requires complicated operations, but this methodology is open to anyone in this world.
